Abstract: Techniques for a service of a cloud computing system to generate and present users with visualizations of computing resources and their network relationships in private networks of the users. The cloud system obtains resource and network connection data from private networks of users and determines overall network architectures for the computing resources and their network connections. The cloud system generates visualizations that represent the overall network architectures for private networks. The visualizations may comprise single pane-of-glass views for users to quickly understand the architectures and networking inside of their private networks. The visualizations may be interactive in that users can interact with visual depictions of resources and be dynamically presented with networking connections and details for the particular resources.
